Dear Lyle,

thank you for your response. Your code works fine.
My problem is shown in the attached screenshot 
of my application. There's a Combobox open, the pane
is in white color, but the first option in it is gray,
like the background. This seems to be because
recursively, labels, textfields, comboboxes get added,
and I set their background color in each iteration step.
Now, it seems that the background is everything but the
newly added textfield,combobox or whatever.
I can work around this problem now, by setting colors
more selectively, as in the lines commented out below.

			next if w.kind_of? TextField
			next if w.backColor==HEADER_COLOR
                        if /ComboBox/.match(w.type.to_s)
                        #elsif /Label/.match(w.type.to_s)
                        w.backColor=STD_BACK_COLOR  # this causes a problem
                        #elsif /Button/.match(w.type.to_s)
                       # w.backColor=STD_BACK_COLOR

So even though I don't understand why this program behaves like this,
it works ,  thank you!

Best regards,
